# Lisa

> A Lisp dialect designed for codingworkshops

## Example

```lisp

(defunc fib-recurse (n)

    (var a 0) (var b 1) (var f 1)

    (defunc calc-fib (i)

        (if (<= i n)

            (do

                (set f (+ a b))

                (set a b)

                (set b f)

                (calc-fib (+ i 1)))

            f))

    (calc-fib 2))

(defunc fib-while (n)

    (var a 0) (var b 1) (var f 1)

    (var i 2)

    (while (<= i n)

        (set f (+ a b))

        (set a b)

        (set b f)

        (set i (+ i 1))

        f))

(= (fib-recurse 10) (fib-while 10) 55)

```
